What else can I help you with?
What can radio telescopes do that optical telescopes cant?
No. The gain of the antenna ... which translates directly into angular resolution ... depends on the wavelength (frequency) of operation.The 2.5 meter optical parabolic reflector (telescope) on Mt. Wilson is a titan. 2.5 meter parabolic radio antennas are routinely used in intercity microwave communication but would be quite useless for serious radio-astronomy, as they are such shrimps at radio wavelengths.
What are the main differences between Schmidt-Cassegrain and Dobsonian telescopes, and which one would be more suitable for my stargazing needs?
Schmidt-Cassegrain telescopes use a folded optical design, making them more compact and versatile for astrophotography. Dobsonian telescopes have a simpler design with a larger aperture, providing better views of faint objects. If you prioritize portability and versatility, go for a Schmidt-Cassegrain. If you want better views of celestial objects, a Dobsonian might be more suitable.
Optical telescopes are designed to collect and create images from is it white or visible light or x rays or infrared radiation or gamma rays?
An "optical" telescope would naturally collect light from optical wavelengths, meaning visible light from ~400-800nm.
Where can someone buy replacement optical lenses?
This may depend on what the lenses are to be used for. Eyeglasses can be fixed at places like Sears Optical. This can also be in reference to telescopes in which case one would have to go to the manufacturer.
Advantage reflecting telescope over refracting telescope?
Reflecting telescopes are typically more cost-effective to build for larger apertures compared to refracting telescopes due to simpler construction and fewer optical components. Reflecting telescopes do not suffer from chromatic aberration like refracting telescopes, leading to sharper images with better color accuracy. Reflecting telescopes can also be made with larger apertures, allowing for better light-gathering capability and higher resolution for astronomical observations.
What would happen if telescopes weren't built?
As Necessity is the Mother of Invention then someone would need to invent a thing which works like a telescope but may go by a different name and might be better than any telescopes we have
Why are most modern telescopes reflecting telescopes?
Most modern telescopes are reflecting telescopes because reflecting telescopes are generally more cost-effective and easier to build at larger sizes compared to refracting telescopes. Reflecting telescopes also suffer less from chromatic aberration and can have a simpler design with fewer optical elements.
Will plugging an optical audio cable directly into the stereo amplifier offer better sound quality than plugging it in from the television or not?
The optical cable would be the best choice.
Which type of telescope is most similar to an optical telescope?
No. The Hubble Space Telescope is an optical telescope of the reflective type. A 'non optical' telescope would be one that works on different portions of the electromagnetic spectrum below or above the optical wavelengths.
What type of telescope uses grazing incidence?
X-ray telescopes use grazing incidence mirrors to reflect and focus high-energy X-rays, which would be unable to be focused using traditional optical lenses. This design allows for better resolution and sensitivity for observing celestial objects that emit X-rays.
State the difference between optical and non-optical telescopes?
Optical measures visible light, Radio measures electromagnetic radiation in that part of the spectrum corresponding to radio waves. Same with X-ray telescopes and x-rays. Optical is the kind you look through.
In what ways would a telescope mounted on the moon be better views into space than a telescope mounted on earth?
a moon based telescope would be better because on the moon there is no wind nor weather so it would be perfect to capture images without worrying about any obstacles.on earth we worry about clouds winds and altitude etc etc.to sum it all up then....... the reason moon-based telescopes are easier to see through is because the moon doesn't have as much obstructions like weather, clouds, pollution, weather, pretty much nuthin.
